Roughly speaking, a diagram is a collection of ‘objects’ denoted by A, B, C, X, Y, ··· , and ‘arrows‘ between them denoted by f , g, ··· , as in the examples f f1 A / B X / Y g g1 f2 h g2 C Z / W We will always have an operation ◦ to compose arrows. The diagram is called commutative if all the composite paths between two objects ultimately compose to give the same arrow. For the above examples, they are commutative if h = g ◦ f f2 ◦ f1 = g2 ◦ g1. Definition 1.1. A category C consists of 1◦. A class of objects: Obj(C) (a category is called small if its objects form a set). We will write both A 2 Obj(C) and A 2 C for an object A in C.

  • Notes for Math 227A: Algebraic Topology
    NOTES FOR MATH 227A: ALGEBRAIC TOPOLOGY KO HONDA 1. CATEGORIES AND FUNCTORS 1.1. Categories. A category C consists of: (1) A collection ob(C) of objects. (2) A set Hom(A, B) of morphisms for each ordered pair (A, B) of objects. A morphism f ∈ Hom(A, B) f is usually denoted by f : A → B or A → B. (3) A map Hom(A, B) × Hom(B,C) → Hom(A, C) for each ordered triple (A,B,C) of objects, denoted (f, g) 7→ gf. (4) An identity morphism idA ∈ Hom(A, A) for each object A. The morphisms satisfy the following properties: A. (Associativity) (fg)h = f(gh) if h ∈ Hom(A, B), g ∈ Hom(B,C), and f ∈ Hom(C, D). B. (Unit) idB f = f = f idA if f ∈ Hom(A, B). Examples: (HW: take a couple of examples and verify that all the axioms of a category are satisfied.) 1. Top = category of topological spaces and continuous maps. The objects are topological spaces X and the morphisms Hom(X,Y ) are continuous maps from X to Y . 2. Top• = category of pointed topological spaces. The objects are pairs (X,x) consisting of a topological space X and a point x ∈ X. Hom((X,x), (Y,y)) consist of continuous maps from X to Y that take x to y. Similarly define Top2 = category of pairs (X, A) where X is a topological space and A ⊂ X is a subspace. Hom((X, A), (Y,B)) consists of continuous maps f : X → Y such that f(A) ⊂ B.

    LECTURES ON DERIVED AND TRIANGULATED CATEGORIES BEHRANG NOOHI These are the notes of three lectures given in the International Workshop on Noncommutative Geometry held in I.P.M., Tehran, Iran, September 11-22. The first lecture is an introduction to the basic notions of abelian category theory, with a view toward their algebraic geometric incarnations (as categories of modules over rings or sheaves of modules over schemes). In the second lecture, we motivate the importance of chain complexes and work out some of their basic properties. The emphasis here is on the notion of cone of a chain map, which will consequently lead to the notion of an exact triangle of chain complexes, a generalization of the cohomology long exact sequence. We then discuss the homotopy category and the derived category of an abelian category, and highlight their main properties. As a way of formalizing the properties of the cone construction, we arrive at the notion of a triangulated category. This is the topic of the third lecture. Af- ter presenting the main examples of triangulated categories (i.e., various homo- topy/derived categories associated to an abelian category), we discuss the prob- lem of constructing abelian categories from a given triangulated category using t-structures. A word on style. In writing these notes, we have tried to follow a lecture style rather than an article style. This means that, we have tried to be very concise, keeping the explanations to a minimum, but not less (hopefully). The reader may find here and there certain remarks written in small fonts; these are meant to be side notes that can be skipped without affecting the flow of the material.

  • Lecture Notes on Simplicial Homotopy Theory
    Lectures on Homotopy Theory The links below are to pdf files, which comprise my lecture notes for a first course on Homotopy Theory. I last gave this course at the University of Western Ontario during the Winter term of 2018. The course material is widely applicable, in fields including Topology, Geometry, Number Theory, Mathematical Pysics, and some forms of data analysis. This collection of files is the basic source material for the course, and this page is an outline of the course contents. In practice, some of this is elective - I usually don't get much beyond proving the Hurewicz Theorem in classroom lectures. Also, despite the titles, each of the files covers much more material than one can usually present in a single lecture. More detail on topics covered here can be found in the Goerss-Jardine book Simplicial Homotopy Theory, which appears in the References. It would be quite helpful for a student to have a background in basic Algebraic Topology and/or Homological Algebra prior to working through this course. J.F.

  • Cofiber Sequences Are Fiber Sequences
    Lecture 7: Cofiber sequences are fiber sequences 1/23/15 1 Cofiber sequences and the Puppe sequence If f : X ! Y is a map of CW complexes, recall that the reduced mapping cone ` is the space Y [f CX = (Y X ^ [0; 1])= ∼, where (x; 1) ∼ f(x). If we vary f by a homotopy, Y [f CX changes by a homotopy equivalence. We may likewise form the reduced mapping cone of a map f : X ! Y in the stable homotopy category. f is represented by a function of spectra f : X0 ! Y , where X0 is a cofinal subspectrum of X. By replacing f by a homotopic map, 0 0 we may assume that fn : Xn ! Yn is a cellular map. Then Y [f CX is the 0 spectrum whose nth space is Yn [fn CXn and whose structure maps are induced from those of X and Y . This is well-defined up to isomorphism, because varying f by a homotopy does not change the isomorphism class of Y [f CX. If i : A ! X is the inclusion of a closed subspectrum, then define X=A be the spectrum whose nth space is Xn=An and whose structure maps are those induced from the structure maps of X. The evident map X [i CA ! X=A is an isomorphism in the stable homotopy category because on the level of spaces we have homotopy equivalences which therefore induce isomorphism on π∗. Definition 1.1. A cofiber sequence is any sequence equivalent to a sequence of f i the form X ! Y ! Y [f CX Proposition 1.2.

  • Global Existence for Quasilinear Diffusion Equations in Nondivergence Form
    GLOBAL EXISTENCE FOR QUASILINEAR DIFFUSION EQUATIONS IN NONDIVERGENCE FORM WOLFGANG ARENDT AND RALPH CHILL A. We consider the quasilinear parabolic equation u β(t, x, u, u)∆u = f (t, x, u, u) t − ∇ ∇ in a cylindrical domain, together with initial-boundary conditions, where the quasilinearity operates on the diffusion coefficient of the Laplacian. Un- der suitable conditions we prove global existence of a solution in the energy space. Our proof depends on maximal regularity of a nonautonomous lin- ear parabolic equation which we use to provide us with compactness in order to apply Schaefer’s fixed point theorem. 1. I We prove global existence of a solution of the quasilinear diffusion prob- lem u β(t, x, u, u)∆u = f (t, x, u, u) in (0, ) Ω, t − ∇ ∇ ∞ × (1) u = 0 in (0, ) ∂Ω, ∞ × u(0, ) = u0( ) in Ω, · · where Ω Rd is an open set, u H1(Ω) and ⊂ 0 ∈ 0 1 β : (0, ) Ω R1+d [ε, ](ε (0, 1) is fixed) and ∞ × × → ε ∈ f : (0, ) Ω R1+d R ∞ × × → are measurable functions which are continuous with respect to the last vari- able, for every (t, x) (0, ) Ω. The function f satisfies in addition a linear growth condition with∈ respect∞ × to the last variable. We prove in fact existence of a solution in the space H1 ([0, ); L2(Ω)) L2 ([0, ); D(∆ )) C([0, ); H1(Ω)), loc ∞ ∩ loc ∞ D ∩ ∞ 0 2 where D(∆D) is the domain of the Dirichlet-Laplacian in L (Ω).

  • Functional Analysis TMA401/MMA400
    Functional analysis TMA401/MMA400 Peter Kumlin 2018-09-21 1 Course diary — What has happened? Week 1 Discussion of introductory example, see section 1. Definition of real/complex vector space, remark on existence of unique zero vector and inverse vectors, example of real vector spaces (sequence spaces and function spaces). Hölder and Minkowski inequal- ities. Introducing (the to all students very well-known concepts) linear combination, linear independence, span of a set, (vector space-) basis (= Hamel basis) with examples. All vector spaces have basis (using Axiom of choice/Zorn’s lemma; it was not proven but stated). Introducing norms on vector spaces with examples, equivalent norms, con- vergence of sequences in normed spaces, showed that C([0; 1]) can be equipped with norms that are not equivalent. Stated and proved that all norms on finite-dimensional vector spaces are equivalent. A proof of this is supplied below. Also mentioned that all infinte-dimensional vector spaces can be equipped with norms that are not equivalent (easy to prove once we have a Hamel basis). Theorem 0.1. Suppose E is a vector space with dim(E) < 1. Then all norms on E are equivalent. Proof: We observe that the relation that two norms are equivalent is transitive, so it is enough to show that an arbitrary norm k · k on E is equivalent to a fixed norm k · k∗ on E. Let x1; x2; : : : ; xn, where n = dim(E), be a basis for E. This means that for every x 2 E there are uniquely defined scalars αk(x), k = 1; 2; : : : ; n, such that x = α1(x)x1 + α2(x)x2 + ::: + αn(x)xn: Set kxk∗ = jα1(x)j + jα2(x)j + ::: jαn(x)j for x 2 E.

Harmonic functions Throughout this section, Ω ⊂ Rn is a bounded domain. 1.1 Definition A function u ∈ C2(Ω) is called subharmonic if ∆u ≥ 0 in Ω, harmonic if ∆u ≡ 0 in Ω, and superharmonic if ∆u ≤ 0 in Ω. 1.2 Notation The measure of the unit ball in Rn is Z n/2 n 2 2 2π ωn = |B1| = |{x ∈ R : x1 + ... + xn ≤ 1}| = dx = . B1 nΓ(n/2) The (n − 1)-dimensional measure of the boundary ∂B1 of B1 is equal to nωn. 1.3 Mean Value Theorem Let u ∈ C2(Ω) be subharmonic, and n BR(y) = {x ∈ R : |x − y| ≤ R} ⊂ Ω. Then 1 Z u(y) ≤ n−1 u(x)dS(x), nωnR ∂BR(y) where dS is the (n − 1)-dimensional surface element on ∂BR(y). Also 1 Z u(y) ≤ n u(x)dx. ωnR BR(y) Equalities hold if u is harmonic. Proof We may assume y = 0.
